SL-510-SSProduct Introduction:

SL-510-SSIt is an upward thermoelectric long wave radiation sensor. The sensor includes a filter, a blackbody thermopile detector, a thermistor, and a self-cleaning sensor housing design.The sensor includes an IP67 marine grade stainless steel cable connector, with a 30 centimeter connector at the head of the sensor, simplifying the disassembly and replacement of the sensor, and facilitating maintenance and recalibration of the sensor.


Typical applications:

Long wave radiation measurement in agricultural, ecological, hydro meteorological networks, and renewable energy applications.


SL 系列向上/向下长波辐射传感器


SL-610-SSProduct Introduction:

SL-610-SSIt is a downward thermoelectric long wave radiation sensor with an analog output range of 0 to 300 mV. This sensor combines a blackbody thermopile detector and a flat glass window with a sturdy housing design. These sensors can be combined with an upward looking solar radiometer to form an albedo meter. For this configuration, it is recommended to use our AL-130 reflectometer mounting bracket. The sensor includes an IP68 marine grade stainless steel cable connector with a 30cm connector at the head, which simplifies the disassembly and replacement of the sensor and facilitates maintenance and recalibration.


Typical applications:

l Short wave radiation measurement in agricultural, ecological, and hydro meteorological networks;

l Used to optimize photovoltaic systems.


Product features:

Ø Accurate and stable measurement:Annual drift<>

Ø Self cleaning:Durable anodized aluminum casing

Ø Self heating:0.2The tile heater can prevent water from flowing out of the sensor and reduce errors caused by dew, frost, rain, or snow blocking the radiation path to a lower level.

Ø Unique design:The filter, blackbody thermopile detector, and thermistor (measuring the temperature of the detector) are all contained in a compact housing.
